On a scale one to ten how would you score on my film concept?

For the last two years I’ve been considering/developing a ‘magical realism’ screenplay about a hidden legendary gemstone that brings good fortune to those who bear it. After it is found in near present day China by an american archeologist, it finds its way to North San Francisco and is rediscovered at an international relics shop called Mantralantis. There and after, a beautiful rare book collector and a well-intentioned antiques opportunist briefly collide romanticly with the charm. Along the way, a bumbling petty thief follows them, waiting for his chance at his own kind of fate. All the while, a man of mystery, popping up seemingly at every turn, seems to guide them all towards an intertwining, uncertain destiny…including himself.
